Specification of Letters Patent.

Patented Dec. 3, 1918.

Application filed August 3, 1816. Serial No. 112,929.

To all whom it may concern:

Be it known that I, CAsrER H. F RALEY, a citizen of the United States,and a resident of Lynden, in the county of Whatcom and State ofl/Vashington, have invented new and useful Improvements in Pumps, ofwhich the following is a specification.

My invention is an improvement in pumps, and has for its object toprovide a pump suitable for use with flowing water and adapted to besubmerged in the water, and having an intake provided with a turbinepropeller which is connected to the pump in such manner that themovement of the propeller driven by the water, will operate the pump,and wherein a double pump is provided, driven by the propeller arangedin a common intake for the pumps.

In the drawings:

Figure 1 is a top plan view of the improved pump,

Fig. 2 is a side view,

Figs. 3, 4 and 6 are sections on the lines 33, 4% and 6--6 respectivelyof Fig. 1, Fig. 4, looking in the direction of the ar rows adjacent tothe line,

Fig. 5 is an end view of the intake, and

Fig. 7 is a perspective View of one of the turbines.

In the present embodiment of the invention, two pumps are provided eachconsisting of a cylinder 1 arranged with the axes parallel, and thecylinders are connected at one end to a valve casing 2 and at the otherend to one of the branches 3 of a Y, consisting of the said branches anda body 4. The Valve casings 2 are connected with the branches 5 of a Ycomprising the said branches and a body 6, and the body is connectedwith the discharge pipe 7. The body 4 of the Y 34 is offset laterallywith respect to the branches 3, and the said body is connected with anintake or propeller casing 8.

A piston 9 is arranged in each pump, each piston having ports providedwith flap valves 10 for closing the same, and a piston rod 11 isconnected with each piston. These piston rods extend out through thebranches 3 of the Y and engage guides 12 on a cross head 13 which issecured to the nipple 14 which connects the common inlet 8 for thepumps, with the body of the Y. This cross head consists of a lowersection 13 and an upper section 13, the lower section having a bed forthe nipple, and the upper section having a U-shaped portion engagingover the nipple, and the said sections having cooperating grooves forreceiving the piston rods 11.

The sections are secured together by bolts and nuts 15. The rods areoperated by a countershaft 1(3 journaled in bearings 17 on the branches3 of the Y. The said shaft is provided at each end with a wheel 18, andeach wheel is connected to the adjacent piston rod by means of a link19'. The link is connected at one end to an eccentric wrist pin on theadjacent wheel, and at the other to a laterally extending pin on theadjacent piston rod, and it will be evident that when the shaft 16 isrotated, in a manner to be presently described, the pump pistons will bereciprocated. The arrangement is such that the pistons will move inopposite directions, and the shaft 16 is provided intermediate its endswith a bevel gear wheel 20 for connection with the propeller shaft to bedescribed.

The propeller shaft 21 is journaled in a bearing 22 at the junction ofthe branches 3 of the Y 3%, and in a head 23 at the end of the intake.and the said shaft has a bevel gear 24 which meshes with the gear 20.Two series of blades is secured to the propeller shaft, each series ofblades havi g a substantially conical hub 25 about which the spiralblades 26 are arranged. The two series of blades are spaced apart fromeach other, and between them the intake pipe is provided with inwardlyextending radial directing vanes or nozzles 27.

The improved pump is arranged as shown in Fig. 2, with the pumpcylinders and the propeller casing immersed, and with the head 23 upstream. This head as shown, is provided with openings of quadrant form,and these openings are covered by a perforated mcmber 28 for strainingthe water to prevent the entrance of sticks, stones and the like. Thewater will enter the open end of the casing and will pass through thecasing, rotating the propeller shaft, after which it will pass onwardinto the pump cylinders.

In operation, with the parts arranged as above specified, the waterpassing through the propeller casing will rotate the propeller oroperating shaft 21. When a piston is moved upward, the water will flowfreely through the ports, while when the piston moves downward, thewater will be driven out of the cylinder by the piston through thedischarge pipe 7 to the place of utilization. The improved pump isespecially adapted for irrigation, being placed directly in the stream,the two pumps receiving water from a common intake and delivering thewater to a common outlet.

In practice, the blades of the turbine are aboutthree' feet in lengthand four blades are used. Since each turbine puts a twist or curve inthe water and gives it a tendency to follow around the pipe, it isessential to. insert the vanes or nozzles 27 to straighten,

thefiow of the water for the second. turbine.

It will be noticed that the section 14 of the casing has overflow orwaste openingsQO.

Iclaim:

In combination, a pair of pump cylinders, a propeller and intake casingconnected with the cylinders at the intake ends of the said cylinders todeliver to the said cylinders, a valved piston in each cylinder, atransmission shaft to which the pistons are connected for reciprocatingsaid pistons, a turbine in the propeller casing, a driving shaft towhich the turbine is connected, and a driving connection between thedriving shaft and the transmission shaft, the pump cylinder being at alower level than the propeller casing.
